Fatented Dec. Q?, i913.

Application .filed August 4, 1913. Serial No. 782,880.

To all 'whom i may concern:

Be it known that l, HARRY J. MARTIN, a citizen of the United States, residing at Glidden, in the county of Carroll and State of Iowa, have invented. certain new and useful improvements in Sash-Fasteners; and l do declare the following to be a full, clear, and exact description of the invention, such as will enahle others skilled in the art to which it appertains to make and use the same,

Qhis invention relates to builders hardware, and more especially to sash fasteners;

and the object of the saine is to produce a device of this character comprising a sliding bolt for each sash and a knob and knob spindle for turning the bolts independently of each other from the inside of the room so as to lock either sash or both sashes in any desired position. rihis object is carried out by constructing the sash fastener in the manner hereinafter more fully described and claimed, and as shown in the drawings wherein- Figure 1 is an elevation of .a window frame containing my invention, taken from the inside of the sash or from within the room. Figs. 2 and 3 are vertical sections through one side of the frame in planes at right angles to each other, and Fig. 4 is a horizontal section on about the line 4-4 of Fig. 2. Fig. 5 is an enlarged detail, taken on the line 5 5 of Fig. 3. Fig. 6 is an enlarged detail of the upper end of the face plate. Fig. 7 is an enlarged perspective detail of the inner end of one of the bolts and the ball and socket connection between it and the bolt at the upper end of its operating arm.

ln the drawings I have illustrated my invention as applied to an ordinary window frame F having outside and inside trims O and l and a parting strip or bead P, the upper and lower sashes U and L sliding at either side of this bead as usual and supported by weights which with their cords are not necessarily illustrated herein.

The object of the invention is to lock these sashes when they are closed or nearly so, and to control the locking or fastening deices from a point inside the room and about opposite the meeting rails of the sashes; and it is the purpose of the invention to carry out this object with the least and smallest mechanism on account not only of the simplicity and therefore the cheapness of parts, hut also because it is desirable that when the attachment is applied to windows already set up their frames and sashes shall not be mutilated and the fastener will not interfere with the proper movements of the weights.

Coming now to the details of the invention, l may say at starting that the mechanism for the sashes is duplicated, and therefore a detailed description of that for one sash will be sufficient. ln the edge ofthe sash is set a plate or strip 1 having a number of holes 2 and preferably secured to the sash by screws 3 passing through it at its extremities and into the edge of the sash. into and through the inner bar B of the frame F opposite said strip 2 is set a socket 4 having a single round hole through it so that it forms a guide for a round bolt 5 whose inner end may be projected into any of the holes 2 and whose outer end extends beyond the socket or guide 4 and is turned aside into a neck 6 having a ball 7 at its extremity.

The numeral 8 designates a socket member loosely receiving said ball and formed at one end of a bolt 9 whose body passes through an eye 10 in the outer end of an arm 11 whose inner end is pinned to or in any way secured upon a spindle 12 as shown. This spindle is rotatably mounted in a tubu- Vlar boss 13 which projects inward from a plate 14 that is secured upon or inset flush with the inner trim I; and, as seen in the drawings the plate is long enough to carry two such bosses 13 so that the two spindles 12 necessary for a two-sash window may be rotatably mounted in one plate. One spindle will be disposed slightly above the other, and the arms 11 properly set thereon so that their socket members may loosely embrace the balls 7 at the inner ends of the two bolts in a manner not necessary to describe in further detail. With a window thus equipped, when the two sashes are moved to or nearly to their closed positions, the holes 2 in the plates 1 pass opposite the tips of the bolts which stand normally retracted. Assuming that the operator desires to lock the window sashes closed, he closes them both and at this time the eXtreme holes in the plates 1 will co-me opposite said bolts and then by turning the spindles in their bosses 13 the boltswill be projected through the guides 4 and the sashes will be locked. My reason for making the bolts 5 round so as to rotatably fit within their sockets 4, and offsetting the f balls 7 by means of short necks 6 will now be apparent. As each spindle rocks on its axis the eye 10 at the outer end of the arm 11 must move through a short arc, and to prevent the bolt 5 from binding in the guide 4, a ball-and-socket connection between the arm and the bolt is provided and it is offset from the axis of the bolt by means of the short neck 6. This, with the normal looseness of parts necessary where oil may not be applied freely, will preventbinding as will be clear.

Another feature of my invention consists in the provision of means for preventing the rotation of the spindle 12 within its boss 13 by jar or vibration, whereby the tip of one of thekbolts might be retracted so that the window could be raised. ll'Chis provision is eiected by stampingv up a short tongue 20 from the plate 14 alongside each point where a spindle passes through it, and providing` the spindle with a ange 21 under its knob or thumb piece 22, the flange having its edge preferably made slightly spiral at one side as indicated at 24. If the knob 22 be flat as indicated in the drawings, the position of parts may well be such that when this thumb piece stands upright the bolt 5 is projected. When now the operator desires to retract said bolt,l he grasps the thumb piece 22 between his thumb and linger and turns it to the right, and this action causes the spiral portion 24 of the flange 21 to pass away from its frictional engagementunder the tongue 2O until the flange is entirely free. At this time the spindle 12 will have made a part revolution in its bearing 13, and its arm 11 will have been movedjfar enough to retract the bolt in the manner above described. The weightof the arm will be suflicient to hold the parts in this position. When now it is desired to again lock the window, the operator grasps the thumb piece 22 between his thumb and finger and forcibly turns it to the left so that the spiral portion 24 is caused to move under and make frictional engagement with thetongue 20, and the parts are restored to the position shown in the drawings.

Another feature is .a sheet metal housing 25 which I preferably employ within the frame F to protect the device from being struck by the weights, butthis might be omitted.

l do not wish to be limited to the precise Vdetails of construction set forth throughout this specification, and obviously the proportions and materials and finish of parts are not essential to the successful operation of the invention.

lVhat is claimed as new is:

1. In a device of the character described, the combination with a tubiila'r guide, and a bolt having a round body slidably and rotatably mounted in said guide and a transversely projecting neck at one end carrying a ball at its outer extremity; of an arm swinging in an upright plane parallel. with but ont of the plane of said guide and having a socket loosely engaging said ball, a horizontally disposed spindle carrying the arm,'and means for oscillating' the spindle. I

2. ln a sash fastener, the combination with a sash having a series vof holes in its edge, a tubular guide opposite said edge, and a bolt having a round body slidably land rotatably mounted in said guide and having at its outer end a transversely projecting neck p`r0- vided with a ball at its extremity; of a horizontally disposed spindle rotatably mounted in the window frame and having a thumb piece at its inner end, a normally upright arm secured at its lower end upon said spindle and having an eye through its upper end, and a bolt adjustably mounted in said eye and having a socket loosely embracing said ball, for the purpose set forth.

3. In a sash fastener, the combination with the sash having a hole in its edge, a bolt adapted to be projected into said hole, a rotary spindle having a thumb piece yat its exposed end, and connections'between said spindle and bolt; of a plate countersunk into the inner trim of the sash-frame and having a boss in which said spindle is journaled and a tongue struck from its body adjacent said j boss, and a flange on the spindle under-its thumb-piece and having atportion of its periphery formed on a spiral, for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
